bolder forl holding open a door of a barn, garage, or otherbuilding,;andhas for its door in either a rigid or resilient manner andsliding loosely through a keeper attachedto theiinder side of the doorlintel, and means for locking the bar in the keeper.

I have shown a convenient form of apparatus in the drawings,whieh are tobe taken as illustrative only and not in a limiting sense, and in thesedrawings Figure 1 is a plan view of the device as applied to a door andframe, showing the door held open.

Fig. 2 is a side elevation, with the parts in the same position as Fig.1.

Fig. 3 is an enlarged detail face view of the mounting braeket, With thelocking bar in section.

Fig. 1 is a similar view of the keeper for the locking bar.

Fig. 5 is an enlarged sectional elevat-ion of one end of the locking barand its keeper as attached to the lintel of a doorway, and

F ig. 6 is a detail of a slight modification.

Referring now to the embodirnent shown,

a door 1 is shown hinged to a wall 2 as of a barn or garage and isadapted to close the opening 3 therein in the usual manner. A plate 1secured to the upper part of the door as by screws 5 is provided with aprojectng stad 6 standing out rigidly from the p1ate through a slackhole in a bracket 7 for a purpose described hereinafter. Also projectingoutwardly in a rigid manner from the plate 4: is a bolt 8 having anenlarged head 9 which retains a ooiled spring 10 on the bolt body.Bracket 7 may thus be rocked Applicfion i1eiSeptembei 12, 1923.

Centering. or 1 This projection, while described as a punehed out orstruck-up portion, may obviously be either ntegral or a separate elementsecured to the bar end, the essential point being that the end of thebar be made larger in one dimension than the dimensions of the slot 16to limit movement of the bar 11 ou twardly through the slot.

A notch 20 is provided on the pivot side of the projeetion 17 and whiehmay be formed in any desired manner. This notch on the upper side of thebar is formed for the purpose of allowing a portion of the member 15 toseat therein, whie h will prevent relative movement between the bar 11and the keeper in either direetion.

A flat spring 18 is scured to the under side of. the bar 11 as by meansof rivet 19 and is adapted to beer against the lower edge of the slot 16in the downwardly projecting portion 15 of the keeper. This causes a11upWard movement of the keeper end of the bar 11, causing a portion ofthe part 15 to enter the notch 20, whioh eeetively holds the door in itsopened position.

I; provide means for causing vertieal mo"ement between the bar andthekeeper, whichmay conveniently take the form of a ehairi 21 attaehedto fiche member 11 on the keeper=side of the DiV ot 12 and whioh maypass through a guide on the door, as shown at 22,andbe seeuredto thedoor as by screw 23. It will now be apparent that a horizontal pull onthat portion of the ohain between the parts 22 and 23 toward the dooropening or in the -direction in whioh the door oloses Will. first oausea depression in the keeper end of the bar 11, thus freeing the keeperfrom the notch 20, and a further horizontal pull on the chain 21 Wi1leause t-he door to close.

It may be found desirable under certain oircumstances to mount thebraokeb 7 rigidly on a plete on the door, such as by provd ng the rightangular porton of the bracket with perforations adapted to re ceve theserews 24 Whi0h securely fasten this member to the door It will bereadily seen, however, that the spring modificatn is to be .preferred,as the spring 10 receives the impact when the door is open to itsfullest extent, and the projeoti0n 17 engages the portion 15 of thekeeper and prevents breakage and undue"strain on the parts.

It has been found that the spring 18 causes a, slowing down of themovement of the door in opening when the spring enga'ges the bottom ofthe slot 16 of the keeper, which serves as. a.=retarding means toprevent a strainirig of the parts at this end.

I claim:

1 A device of the charactr described, inclu dii1g 2i keeper secured to udoor 1intel, a bar' sliding in. a slot in said keeper, seid bar beingpivotally carried on a door, and

means hevi ng fixed engagement -with said bar, and a fixed and slidingengagement .with said door and responsive to a horizontal pull fortransmitting vertical motion to sad bar.

2. A device ofthe oharacter desoribed, in-

cluding a keeper seeured to a door lintel, a

bar sliding in a slot in said keeper, a notch in thetop of said bar, andspring means to cause said keeper to enter said notch, a bracket looselypivoted to said bar, a piate secured to the door having a boltprojeeti1ig therefrom and passing through said bracket,

end spring Ineens between a head on said" bolt and said braeket.

3. A device of the charaoter desribed, in-

cluding a keeper attached to a door 1intel, a bar sliding in a slot insaid keeper, a projection on said bar engaging seid keeper,

a notch in the top of said bar, spring meat1s secured to the bar, abearing on the keeper GEORGE LANE{
